Android : Holding down a button for repeated action -- is there an android:onClick for holds? (in XML files)

Hopefully the question says it all... I've been searching the web for an easy solution, I'm surprised to see there isn't? I expected this to be a basic functionality that I could just add into the XML file? Alternatives are welcome, but I already know they're out there. I just want to know if this simple method is possible (couldn't seem to find anything in the documentation but who knows)
